DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Referring to FIGS. 1 and 2, the rack assembly of the present invention comprises four columns 10, a top frame module 20 and a bottom frame module 30, so as to reduce the room required when in transportation and the ability for management of load is also increased.

As shown in FIGS. 2 to 5, the top frame module 20 comprises a top frame 21, a top connection unit 22 and at least four top fixing slots 23. The top connection unit 22 has multiple top connection parts 221 which are connected to the inside of the top frame 21. The at least four top fixing slots 23 each are formed by connections of the top frame 21 and the top connection parts 221, and the four columns 10 have their respective four first ends inserted into the at least four top fixing slots 23. Each of the four columns 10 and each of the at least four top fixing slots 23 are secured by at least one top locking unit T1 so as to secure the relative position between the column 10 and the top fixing slot 23. The top frame 21 has a first top U-frame 213, a second top U-frame 214, a first top connection plate 215 and a second top connection plate 216. The first top connection plate 215 connects the first top U-frame 213 to one end of the second top U-frame 214. The second top connection plate 216 connects the first top U-frame 213 to the other end of the second top U-frame 214. By using the top connection parts 221, the first top connection plate 215 and the second top connection plate 216, the top frame module 20 can support more load than the conventional rack assemblies.

As shown in FIGS. 4 to 8, the bottom frame module 30 comprises a bottom frame 31, a bottom connection unit 32 and at least four bottom fixing slots 33. The bottom connection unit 32 is connected to the bottom frame 31 and comprises multiple bottom connection parts 321. The at least four bottom fixing slots 33 are formed by connections of the bottom frame 31 and the bottom connection parts 321. The four columns 10 have their respective four second ends inserted into the at least four bottom fixing slots 33. Each of the four columns 10 and each of the at least four bottom fixing slots 33 are secured by at least one bottom locking unit T2. The bottom frame 31 has a first bottom U-frame 313, a second bottom U-frame 314, a first bottom connection plate 315 and a second bottom connection plate 316. The first bottom connection plate 315 connects the bottom top U-frame 313 to one end of the second bottom U-frame 314. The second bottom connection plate 316 connects the bottom top U-frame 313 to the other end of the second bottom U-frame 314. By using the bottom connection parts 321, the first bottom connection plate 315 and the second bottom connection plate 316, the bottom frame module 30 can support more load than the conventional rack assemblies.

As shown in FIGS. 3 to 5, each of the top connection parts 221 has at least one top notch 2211 and the top frame 21 has at least four top corners 211 which are located corresponding to the at least four notches 2211 so as to form the at least four top fixing slots 23. The top frame 21 and the top connection part 221 are in contact with each other in face-face manner so that the load is supported by the top locking units T1, the top frame 21 and the top connection part 221.

As shown in FIG. 7, each of the bottom connection parts 321 has at least one bottom notch 3211 and the bottom frame 31 has at least four bottom corners 311 which are located corresponding to the at least four bottom notches 3211 so as to form the at least four bottom fixing slots 33. The bottom frame 31 and the bottom connection part 321 are in contact with each other in face-face manner so that the load is supported by the bottom locking units T2, the bottom frame 31 and the bottom connection part 321.

As shown in FIGS. 5 to 7, the top frame 21 has a top bent wall 212 extending downward from the inside thereof and the bottom frame 31 has a bottom bent wall 312 extending upward from an inside thereof. The top and bottom bent walls 212, 312 reinforce the connection between the top connection parts 221 and the top frame 21, and between the bottom connection parts 321 and the bottom frame 31.

As shown in FIGS. 4 to 9, each of the top connection parts 221 has a top locking plate 2212 and each of the bottom connection parts 321 has a bottom locking plate 3212 which is located corresponding to the top locking plate 2212 so as to be connected to four links 40. The links 40 are used to position the electric devices in the rack assembly. Each of the top locking plate 2212 and the bottom locking plate 3212 has an elongate hole so that the links 40 can be fixed at different positions along the elongate holes to adapt the sizes of the electric devices.

FIGS. 9 and 10 show that the top locking unit T1 comprises a male bolt and a female bolt, the male bolt and the female bolt respectively extend through the top frame 21, the top connection part 221 and the column 10 to connect the top frame 21, the top connection part 221 and the column 10. Similarly, the bottom locking unit T2 comprises a male bolt and a female bolt, the male bolt and the female bolt respectively extend through the bottom frame 31, the bottom connection part 321 and the column 10 to position the bottom frame 31, the bottom connection part 321 and the column 10.

As shown in FIGS. 6 and 7, the bottom frame 31 is connected with a roller unit 50 by which the rack assembly is moved easily.

The rack assembly is easily assembled and disassembled, and the room required for transportation and storage is reduced. The strength of the rack assembly is reinforced to accept more electric devices.
